One is for internet connection, wich is PPPoE, the other one is for a PPPoSSH session - to connect to my company via a VPN. During startup, I enabled ppp to dial to Internet in the rc.conf script. # PPPoE for DSL ppp_enable=YES ppp_mode=ddial ppp_nat="no" ppp_profile="arcor-dsl" ppp_user="root" When I want to connect to my company I simply start ppp. PPP then answers with an error message which kills my PPPoE session to the Internet. The error messages logged by /var/log/messages Aug 20 17:23:40 circa ppp[935]: Error: bundle_Create: ioctl(TUNSIFMODE): Device busy Aug 20 17:23:45 circa ppp[225]: tun0: Error: ip_Input: deflink: wrote 56, got 0 Aug 20 17:23:47 circa last message repeated 3 times Aug 20 17:23:47 circa ppp[225]: tun0: Warning: iface rm: ioctl(SIOCDIFADDR, 213.23.24.183 -> 145.253.4.4): Can't assign reques ted address I then have to kill my ppp, start the internet again and then open the PPPoSSH session. After the first fail, everything is fine. So I have to go through this procedure only once - just after reboot. >How-To-Repeat: To have a full documentation, here is my ppp.conf # # ppp.conf: PPPoE configuration # default: set log phase tun # download /etc/resolv.conf #enable dns arcor-dsl: # PPP over Ethernet set device PPPoE:rl0 set speed sync set mru 1492 set mtu 1492 set ctsrts off # monitor line quality enable lqr # log just a bit set log phase tun # insert default route upon connection add default HISADDR # User / Pass set authname * (changed for report) set authkey * (changed for report) sparta: set device !/etc/ppp/sparta set speed 115200 set mtu 800 allow users root hannes raveboy set timeout 0 set log phase chat connect lcp ipcp command set dial set login set ifaddr 192.168.3.1 192.168.3.2 set server /var/tmp/loop "" 0177 And the "/etc/ppp/sparta" file #!/bin/sh exec ssh -C -c blowfish raveboy@82.**.**.77 -i ~/.ssh/raveboy\@sparta.key '/usr/sbin/ppp -direct scheme' (IP Changed, becaus I don't want to show it to public!) >Fix: Okay, here are the commands from the shell ppp quit ps ax|grep ppp 941 ??
